求问GMAT OG12 CR77题
Country Y uses its scarceforeign-exchange reserves to buy scrap iron for recycling into steel.Althoughthe steel thus produced earns more foreign exchange than it costs,that policyis foolish.Country V's own territory has vast deposits of iron ore,which canbe mined with minimal expenditure of foreign exchange.
Which of the following,if true,provides the strongest support forCountry V's policy of [l1] buying scrap iron abroad?
(A) The price of scrap iron oninternational markets rose significantly in 1987.
(8) Country V's foreign-exchangereserves dropped significantly in 1987.
(C) There is virtually no difference inquality between steel produced from scrap iron and
that produced from iron ore.
(D) Scrap iron is now used in theproduction of roughly half the steel used in the world today,and expertspredict that scrap iron will be used even more extensively in the future.
(E) Furnaces that process scrap iron can be built and operated in Country Y with substantially less foreign exchange than canfurnaces that process iron ore.
E.但D为什么不对呢,E意思是 在Y国建立可处理iron的火炉比处理iron需要更少的外汇 它对结论有什么支持作用呢?

D范围错了.支持必须要支持结论,这点你也明白.这问题的结论是Country Y uses its scarce foreign-exchange reserves to buy scrap iron for recycling into steel
is foolish.
D选项focus on这个技术以后会不会广泛使用,为无关选项.
E说的是处理scrap iron比处理iron ore成本更低.原文关注的就是钱的问题,无论是否支持,这个选项首先在范围上是对的.并且,这道题仅仅通过范围的判断就可以排除其他四个选项了.如果不放心,你可以继续判断E选项的方向,通过对process成本的比较显然可以得出它是支持原文结论的.另外E的意思不是建立炉子需要更少的外汇,而是built and operated.逻辑读题必须要仔细.
最后举个简单的例子,假设原文是:我要买车,朋友建议说我应该买大众而不是尼桑.
这里有一个选项是:大众车的空调和尼桑车的空调一样好.
这个选项在这里是起到support的作用的.因为这里“大众车的空调和尼桑车的空调一样好”是作为“封堵了一种weaken的可能性--即大众车的空调可能没有尼桑车的空调好“而起到support的作用的,即排除他因.你发的这道题的support选项也是这个类型,即”自产的成本不会比引进的高“,从而支持应该自产的结论.
通过做题你可以发现这种类型的support会经常出现,如果你做一个归纳也可以发现support大致会有这么几种,排除他因,事实平行举例,与措施结合促进结果,以及扩大二者比较差距.
E意思是:在Y国建立加工铁屑(scrap iron)的火炉比建立加工铁矿石( iron ore)的火炉需要更少的外汇,D意思是:当今世界,铁屑在生产中的使用大致相当于钢铁的一半,而专家预测,铁屑在未来会被更广泛的应用。据此,可以看出,E强调:生产铁屑比生产铁矿石成本更低,而D则强调铁屑的应用前景较好,根据本段第一句,Y国买铁屑的目的是为了加工钢铁,并不是生产铁屑,这与D选项的意思相悖,不知这样解释...
